Luteinizing hormone (LH, also known as luteinising hormone, [1] lutropin and sometimes lutrophin [2]) is a hormone produced by gonadotropic cells in the anterior pituitary gland. The production of LH is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. [ 3 ]
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production. [1]
During the initial phase of luteinizing hormone-releasing hormone (LHRH) agonist therapy in individuals assigned male at birth, there is a notable phenomenon known as the "flare." This occurs when testosterone levels temporarily surge by approximately 50% within the first 1 to 2 weeks of therapy.
But it may also cause side effects like skin irritation (particularly with gels), a high red blood cell count, acne, hair loss, and male infertility. TRT has also been linked by some reports to ...
GnRH modulators affect the secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn affects the gonads, influencing their function and hence fertility as well as the production of sex steroids, including that of estradiol and progesterone in women and of testosterone in men.
Men and women exhibit different symptoms for hypergonadism. A few of the symptoms that men can experience are increased sex drive, early balding, excessive muscle mass, and acne. Women can have symptoms such as, increased growth of facial hair, deepened voice, coarse body hair, and an irregular menstrual cycle.
Degarelix, sold under the brand name Firmagon among others, is a hormonal therapy used in the treatment of prostate cancer. [3] [5]Testosterone is a male hormone that promotes growth of many prostate tumours and therefore reducing circulating testosterone to very low levels is often the treatment goal in the management of advanced prostate cancer.
A dosage of 100 mg/day CPA can achieve a 65 to 70% reduction in sebum excretion rate in males within 4 weeks of treatment, but doses of 10 mg/day CPA or less are said to have a negligible effect. [ 57 ] [ 58 ] On the basis of these findings, it has estimated that the threshold dosage of CPA to reduce sebum production may be 5 mg/day in males ...
